Application of a fuzzy rule-based method for the determination of clay dispersibility

Examination of the Physico-chemical Composition of Dispersive Soils

“…However, this classification method requires at least 60% of the exchangeable cations to be sodium, which is relatively high. Another research [22] have shown that dispersive behavior was observed with less sodium than Sherard's method suggests.…”

“…In the recent years extensive research have been carried out out to get a better understanding of the reasons related to the dispersive behavior [6,21,22]. Therefore the investigation of physical and chemical properties have been made.…”

Application of fuzzy logic to Boolean models for digital soil assessment

“…The case studies in Sections 5 and 6, respectively, illustrate the one-stage and the two-stage methods. The case studies by Kaufmann et al (2009) andZorluer et al (2010) follow the two-stage method.…”

“…Our tentative conclusion is that piecewise linear functions are most suitable for applications in soil assessment. Kaufmann et al (2009) and Zorluer et al (2010) use this type of function too.…”

Modeling of Soil Cation Exchange Capacity Based on Fuzzy Table Look-up Scheme and Artificial Neural Network Approach

“…Burrough et al (1992) demonstrated that fuzzy classification produced a superior number of available areas for agriculture compared to conventional Boolean classification. Zorluer et al (2010) investigated the application of a fuzzy rule-based method for determination of clay dispersibility. In this study, a fuzzy logic approximation method was developed to combine the different results of the double hydrometer, pinhole, Na (%)-TDS and ESP-CEC methods into a single value.…”
